Application filed October 22, 1927. Serial No. 228,055

The present invention relates to a strain equalizing device, particularly adapted for use where it is necessary or desirable to produce an equal pull upon a pair of wires or cables, as in fences, telephone or telegraphic wires.

The device is characterized by the fact that the pull on the pair of wires may be equalized. This result is produced by an exceedingly simple, strong and durable structure embodying a frame of arcuate formation with pulleys at the ends thereof and a chain or the like trained over said pulleys and means for engaging the frame with a stretching mechanism.

A still further very important feature of the invention resides in the provision of a device of this nature which is thoroughly efficient and reliable in .use, easy to manipulate, and otherwise well adapted to the purpose for which it is intended.

lVith the above and numerous other objects in View as will appear as the description proceeds, the invention resides in cer tain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing: Figure 1 is an elevation of the equalizer embodying the features of my invention,

Figure 2 is another elevation thereof taken at right angles to that shown in Figure 1, and r I Figure 3 is an enlarged detail sectional view taken substantially on the line 33 of Figure 1. Referring to the drawing in detail it will be seen that the frame F is formed of a pair of arcuate strips of flat like metal or other strong and suitable material, each strip being denoted specifically by numeral 5. The major portions of these strips 5 are disposed alongside of each other in abutment and held firmly together by a plurality of rivets 6. The extremities of these strips, however, are offset laterally to provide spaced parallel ears 7 between which are journaled pulleys 8. The strips 5 are formed with registering openings 9 and links 10 are engaged therewith and engaged with a ring 11. A chain or other suitable flexible element 12 extends between the ears 7 and is trained over the pulleys 8. At the extremities of the chain 12 there are mounted wire engaging elements 14:.

The ring 11 is adapted to be engaged by a .wire stretching mechanism or the like and the pull on the ring 11 caused by said mechanism will be imparted through the links 10. to the frame F and equalized through the chain 12 to the wire engaged in the elements 7 14 as will be quite apparent.

The present embodiment of the invention I 1. A strain equalizer of the class described comprising an arcuate frame, pulleys journalled in the ends of the frame, a chain trained over said pulleys, wire engaging elements on the extremitiesof the chain.

2. A strain equalizer of the class described comprising an arcuate frame, pulleys journalled in the ends of the frame, a chain trained over said pulleys, wire engaging elements on the extremities of the chain, a pair of links engaged with the frame equidistant from the center thereof, and a ring engaged with the extremities of the links.

3. A strain equalizer of the class described comprising a frame formed from a pair of arcuate stripsdisposed in abutment with each other throughout the major portion of their length, means securing said major'portions together, the ends of the strips being offset laterally to form spaced parallel ears, pulleys journaled between the cars, a chain trained over said pulleys, wire engaging elements on the extremities of the chain.

. 4. A strain equalizer of'the class described comprising a frame formed from a pair of arcuate strips disposed in abutment with" each other throughout themajor portion of their length, means securing said major portions together, the ends of the strips being ofi'set laterally to form spaced parallel ears,

pulleys journaled between the ears, a chain 5 trained over said pulleys, wire engaging elements on the extremities of the chain, said major portions of the strips being formed GOTTHILF J. i RENLEQ
